Number / Alarm Cause
A131 Control signal [OFF1] was deactivated while a
traversing command was being executed.
OFF1 missing Effect:
The drive is brought to a standstill via a ramp
(P464 Deceleration Time). There is a
subsequent pulse disable. This also valid if
P443 =0 (function diagramm 310) and the
ramp generator bypass (function diagramm
320) is used.
A132 -Control signal [OFF2] was deactivated while a
traversing command was being executed.
OFF2 missing
-Checkback signal [OFF2] was deactivated
while a traversing command was being
executed.
Effect:
The pulse disable is initiated immediately. If
the motor is not braked, it coasts down.
A133 -Control signal [OFF3] was deactivated while a
traversing command was being executed.
OFF3 missing
-Checkback signal [OFF3] was deactivated
while a traversing command was being
executed.
Effect:
The motor decelerates at the current limit.
There is a subsequent pulse disable.
A134 The "enable controller" [ENC] control signal
was deactivated while a traversing command
Enable Controller ENC was being executed (control bit No.3 "Inverter
missing Enable", refer to function diagram, sheet 180)
Effect:
The pulse disable is initiated immediately. If
the motor is not braked, it coasts down.
A135 Actual position value not o.k. from position
sensing (B0070 / B0071)
Actual position value
not o.k
A136 Machine data 1 (position encoder type/axis
type) was changed.
Machine data 1
changed - RESET Effect:
necessary The activation of traversing commands is
inhibited.
A137 The same axis assignment (machine data 2)
was entered for several axes (M7 only, not
Axis assignment significant for the F01 technology option).
incorrect
Effect:
The activation of traversing commands is
inhibited.

SIMOVERT MASTERDRIVES Operating Instructions
Counter-measure
Check the activation of control signal [OFF1]
from the user program.
-Check the activation of control signal [OFF2]
from the user program.
-If checkback signal [OFF2] is missing, check
the supply of control word 1 (MASTERDRIVES
function diagram, sheet 180).
Note:
To activate the "in operation" [IOP] status
again, you must deactivate [OFF1] and then
activate it again.
-Check the activation of control signal [OFF3]
from the user program.
-If checkback signal [OFF3] is missing, check
the supply of control word 1 (MASTERDRIVES
function diagram, sheet 180).
Note:
To activate the "in operation" [IOP] status
again, you must deactivate [OFF1] and then
activate it again.
Check the activation of the "enable controller"
[ENC] control signal from the user program.
-Check interconnection of B0070 and B0071,
-check position encoder and evaluation board,
-check encoder cable.
If machine data 1 has been changed, the
"reset technology" [RST] control signal must
be activated. Alternatively switch the
MASTERDIVES electronic power supply off
and on again
A unique axis assignment must be entered for
all axes on an M7-FM. For example, it is not
allowed to define two X axes.
